"assenso,

To all whom t may concema -g' if' Be it known that I, RALPH- ;STUDDBDa-a citizen of the United States of Arnerica,re siding at Double Springs, in theaccunty of Winston land State of Alabama,g havev in,- `vented certain new and useful'lmprovements in Attaclunents for Carbureters, Vof'which ythe following is' a specification, reference being had therein totheaccompanying drawing.

This invention relates .to -.carbureters. and has for its object the production of a; simple and eiicient fuel attachment adapted to' be used in connection with carbureters andthe like whereby oil or kerosene may be used in producing an ecientexplosive medium in place of gasolene. y

Another object of this invention is the production of a simple and `eiiicient. means for gasiying oil or kerosene as the-same passes through the carbureter and to the in.- take manifold. 3

With these and other objects inview this invention consists of certain novel combinations, constructions and arrangementsv of parts as will be hereinafter fuly described In the drawings Y j i 'Figure 1 is a side' elevation being partly shown diagrammatic, showin the arra ement of the several pipesleadmg to the carbureter and intake :and exhaust manifolds;

ent invention;

Fig. 2 is a vertical sectionthrough the main valve casing for controlling the admission of kerosene and oil to the carbureter A Fig. 3 is lan enlarged section taken on the line 3 3 of Fig. 1, looking in the direction of the arrow. v I

Fig. 4 is a vertical section through the Suction pump used in connection with the presv Fig. 5 is a section taken on the line 5-5 of Fig. 1; y I

Fig. 6 is a section taken on the line-- ofFg.1;. i

Fig. 7 is a plan view of the operating lever and support which controls the opening and closing of the main control valve.

By referring to the drawings it will be seen that 1 designates the casing of the main con; trol valve within which casing 1 is mounted an elongated tapering rotary valve 2 as clearly illustrated in Fig. 2 of the drawing. This casing 1 is provided with a kerosene er.. fulrassage 3.a heated air. Passage.- ,4'

and awater passage '5eiiteniding.transversely therethrough, A pipe disconnected to and communicates'wit the keroseneor fuel pas sageB. and iS adapted to fitto the carbureter 7 :as will be clearly understood Vby carefully ccnsidering Fig, v1 of the drawings. The p1p e 10 is also connected to the valve casing 1; and' 4communicates with the water pasto .it .somewhat closely in-engagement with the plpes 6 and 10 for 'the Vpu'rposeof heating thesepipes 6 and 10 and thereby addin to the gasification of the kerosene or fue which passes through the .pipe 6 and .also assisting' in heating the air passing through theppe 10. 1The valve .2 is of course provided with vsuitable registering apertures or .ports -1'4 for. forming a communication and onstituting a continuous passage through .t e passage ways 3, 4 and. 5 as illustrated clearly in Fig. 2 of the drawings.

The Water supply pipe 10 carries a nozzle 15 at its upper end and this nozzle 15 is provided with: a forwardly projecting threaded end I16 which is formed into the intake car-- bureter 11 as shown in detail in Fig. 6 for the purpose of discharging or injectlng water intothe intake manifold 11 as the fuel passesftherethrough. The nozzle 15 is of course provided with a 4'suitable passage way or Vport 17 to permitl-the free passage of steam or water therethrough. A needle valve .18 is adjustably supported withinthe nozzle 15 and is adapted to regulate the size of the discharge opening 19 formed in the discharge end of the nozzle 15. A suitable head 20 is formed upon the outer end of the needle valve 18 for facilitating the operation ofthe needle valve andthe proper positioning'thereof. A suitable packing 21 is carried by the nozzle 15 and ts snugly around the needle valve :18 to prevent leakage therethrough. It of course, should Abe understood thatsuitable unions or packings are formed around the junctions of all ofthe prpesnsed in connectionnvith the presantdesage 5 for .conveying water to the intake l a packing 23 to which the heated air pipe l the exhaust gases to be readily. and conveniently conveyed from the exhaust manifold 9 and through the pipe 8 to the'muiiler 13.

The carbureter'. 7 is directly connected to the mtake manifold 11 as shown in Fig. 1

and the c .arbureter 7 also carries aheating supply plpe 24 which heating supply.l pipe 241is connected by means of'a' T-)omt 25 -to the outerend of the exhaustmanifold 9-thereby conve ing heated air to the carbureter 7 for t e purpose of maintaining the proper temperature within the carbureter. v

The casing lis provided with a gasolene intake passage'-26, which gasolene intake passage 26communicates with a vertically extending passage 27,1 the passage 27 'also communicating with the discharge end of the passage 3'bef0re described. A suitable port 28 is formed in the rotaryl valve 2 and this port extends at an angle to the ports A1'4 previously described in order to prevent the passage of gasolene into the passage way 3while the passage ways 1'4 communicate withf the passage ways 3, 4 and 5. A suitable "gasolene, supply pipe 29 is con' nectedto the casing 1 and communicates with the passage way 26 andthispipe 29 isconnected to a gasolene 'supply tank 30 'v illustrated in Fig. 1. Theca'sing 1 is provided with a vertically extending entrance opening -31 'which is normally closed by means of a plug32. It should be understood that the vertically extending passage 27 may be readily cleaned by the removal volif-this plug? should the passage become clogged.

The rotary valve 2 is provided with a reduced lower end 33 upon which is mounted a coiled spring A3,4 for the purpose of maintaining the rotary valve 2 snugly within the casingr 1. This valve 2 is provided with a socket 35 at the upper end thereof within which socket 35 is mounted a head 36 held firmly therein by means of locking screws 37. An operating rod 38 is universally connected to this head 36 and this rod 38 f is in turn connected to the operating handle 39. This operating'handle 39 is -pivotally mounted upon a' gage plate 40 which' gage plate is provided with suitable legends thereon for permittingtheoperator to determine the proper position of the rotaryvalve 2 within the casing 1. When the operating lever 39 is swung toward the right-so as to overhang the legend reading "waten air or kerosene,l the kerosene and ating lever 39""is swung toward overhang lthe legend gasolene, all of the 8 is connected for the purpose of permitting Laeaeeo lintake manifold as will be obvious by carefully considering Fig. 1. When the operthe left to ports in the valve 2 will be closed to the .re- 'spective'passageaways'formed in the casing 1 with the exception of the port 28 which 'will open the passageway 26 and permit the How of' gasolene'from the pipe 29 down lthrough the passage way 27 and out through the' pipe '6to the carbureter.' There is still another' legendplaced in the center of the gage plate 40 which is entitled pump and by swinging thele'ver 39 to a central positionv the port 41 at'the lower end of the valve 2 will 'be thrown to 'such position as to form a communication and a continuous passage through the passage way formed 1n .the bottom of thecasing 1. -This passage way 42 communicates 'with' vthe bottom of the carbureter 7 by means of a suction pipe 43 and the opposite" end of the passage 42 communicates with the bottom'of'the suction pump 44 by means of a pipe 45. y

The upper end ofthe pipe 45' engages a valve casing 46 within which'valvel casing is :mounted a spring pressed ball valve47 which "is adapted to normally remain in a, closed position. The.,'casing 46 is connected directly to the bottomgof the .pump casing 44 'and -a discharge valve'casing 48 is connected to the side of the pump -casing 44 asl shown in Fig. 4 of the drawings. The spring pressed ball valve 49v is carried by the casing 48 and is adapted vto normally remain in a closed position and prevent the 'assage of liquid through the casing 49 into the pump casin 44. A discharge pipe 50 is connected tot e casing 48 and is in turn connected to' the top of the kerosene Supply tank l51 shown clearly in Fig. 1 of the drawings.

The passage way formed in the casing 1 is connected at its outer end'with a-pipe 52 which pip'e52 communicates with a water supply tank 53, which tank may be placed in anyJ suitable or convenient position ,provided the same is not placed above the discharge end of the pipe 10 or in fact above the nozzle 15. The suction maintained Within the intake manifold 11 will be suflicient to draw sufficient water for' proper mixtureinto the intake manifold 11.

The operation of the device is as follows: In the usual starting of the engine it may be preferable to admit gasolene into the carbureter in order that a proper mixture of fuel may be-.obtained The operating lever 39 is then swung to the position for closing all of the ports in the rotary -valve 2 with the exception of the port 28. This will admit the low ofgasolene from the --tunk lli meente .30 through the pipe 29 through the casing 1 to the pipe 6 and `into the carbureter 7 and from the carbureter 7 through the intake manifold v11 to the cylinders of the engine. -When it is desired to cut off the supply of gasolene the lever 39 is then swung toward theleft as shown in Fig. 7 thereby closing thefportf28 and opening the-ports 14 of the valve 2. This will .permit the passage of kerosene from the tank 51 through the pipes 6 and casing 1 and intake carbureter 7 At the :same time; water will pass from the tank 53 through the pipe 52, casing 1, pipe 10 and be injected into the intake manifold 11 through the nozzle 15. At the same time heated air or exhaust gases will pass through the pipe, 8 from the elbow 22 and exhaust manifold 9 through the casing 1 and passage way 4 through the pipe 12 and out through the muffler 13.l When it isagain desired to admit gasolene into the carbureter 17 the lever 39 is swung to a central or neutral p0- sition thereby closing all of the ports with the exception of the port .41 of the rotary valve 2. The' pump 44-mayf then be oper.- ated byreciprocating the plunger 5.4 within the casing 44. This will draw the kerosene from the carbureter 7 due 4to the factthat the pipe is connected tothe bottom of the carbureter 7 and draw the kerosene .into the casing 44. -Upon the return stroke of the plunger 54 the kerosene will be forced out through theyalve casing 48 and into the kerosene reservoir 51 through the pipe 50.

The lever 39 may then again be thrown toward the left for the purpose of pumping gasolene to the carbureter.

From the foregoing description it will be seen that a very simple and eiiicient means has been produced for ermitting the use of kerosene orsimilar with explosive engines and the like and at the same time producin an eiiicient explosive medium for admitting the same to the cylinders of the engine.

It should be understood that in actual usethe pipes 6, 8 and "10 'may be wrapped together for the urpose of retaining as much heat as possible but it is thought unnecessary to show this wrapping for the reason that it is common to connect or wrap pipes for'A the purpose of retaining the heat units., However it is important that the pipes 6, 8 and 10 should be arranged in close proximity to each other'in order that the greatest amount Aof efficiency may be obtained. It is of course understoodthat the usual needle valve 55 is carried by the carbureter 7.

By carefully considering Fig. 2 of the drawings, it will be seen that a plurality of apertures 14 are formed in the casing 1 for the purpose of permitting bolts or other securing means to pass therethrough, thereby permitting the casing 1 to be eiiciently nel in connection supported upon. orattached to the motor of an; automobile or ,the like.
